RArLRoAD TIE.

Application :tiledI August 18, 1926. Serial No. 130,051.

This invention has for its object the provision of a durable and inexpensive railroad tie which may be easily placed in position to support a railroad track and which will have sound-deadening characteristics. The invention is illustrated in the accompanying drawings and consists in certain novel features which will be hereinafter first fully described and then more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a perspective view of a rail road tie embodying my invention;

Fig. 2 is a central vertical longitudinal section of the same;

Fig. 3 is a transverse section, and

Fig. l is a. horizontal section on the line 4-4 of Fig. 2.

The tie consists essentially of a box or body member 1 and a top or cover member 2 which are of metal and may be painted With weather-resisting material so asto withstand corrosion. The body or box member 1 is cast in one integral structure with a transverse partition 3 rising from its bottom and terminating flush with t-he upper edges of its sides and ends, the box being preferably rectangular and of proper dimensions to extend across the roadbed, as will be understood. The top or cover member 2 is likewise an integral casting comprising a flattop plate and side and end walls 4 and 5, respectively, depending from the under-side of the top plate. The side walls i are flush with the longitudinal edges of the top plate, but from the centers of the end walls at the top thereof project as lugs 6 having openings 7 therethrough while from the side walls at the top of the same and spaced apart a distance corresponding to the gage ofthe road are lateral tongues or supports 8 which furnish an extended support for the track rails 9, it being understood that the projections 8 are provided on both sides of the tie and the corresponding projections are in alinement. The said supporting projections have openings 10 formed therethrough to accommodate bolts 11 which have lateral heads 12 at their upper ends adapted to project over the base flanges of the rails and are equipped at their lower ends with nuts 13 adapted to be turned home against the under sides of the projections whereby to firmly clamp the rails in place.

The interior of the lower box or body member 1 is illed with paper :or similar material, indicated at 14, which material is compressed and is preferably arranged in layers, as clearly shown in Figs. 2 and 3. This cushioning and sound-deadening material is provided in sufficient quantity to entirely fili the 'box and the uppermost layer 15 thereof extends across the top of the partition 3 and across the end walls of the fbox so as to lie flush with the outer surfaces of the box, as will be understood upon reference to Figs. 2 and 3. When the entire tie has been assembled and placed in position, the upper or cover member does not rest directly upon the lower member but the layer 15 forms a sound-deadening cushion between the of;- posed metallic surfaces so that the noise incident to the passage of trains is minimized and practically eliminated. The vibration in the cars due to the high speed in traveling over the track rails is very materially rellued by the provision of this cushioning In the use of the tie, the cushioning material is placed in the lower body or box member and the cover then assembled therewith. hen the tie is to be placed in the roadbed, vthe openings 7 provide means whereby a pick or other tool may be readily engaged with the tie and a pull exerted upon the tie to drag it into its proper place in the roadbed. The ballast of the roadbed may be packed around the tie in the usual manner so that displacement of the tie cannot readily occur. Itwill be noted that the cover or top member entirely surrounds the box or lower body so that it will be effectually held against accidental removal from the box and the latter is, of course, buried in the roadbed so that it will be firmly anchored. The projecting rail-supporting lugs or plates 8 are easily accessible to facilitate the placing of the rail securing anchor' bolts 11 so coA that the nuts 13 may be easily turned home tegral With its side Walls and having its upper edge flush Wit-h the upper edges of the side Walls of the box, a cover extending over the entire box and having depending Walls fitting around the sides and ends of the box, laminated cushioning material entirely lling the box and extending across the upper edges of the Walls of the box and the partition and lling the space between said edges and the under side of the cover, supporting plates integral With and projecting laterally from the sides of the cover flush with the top of the same, and rail-anchoring elements extending through said plates and secured at the under sides thereof.

In testimony whereof I ax my signature.
